Intermediate Python
Class Duration
- 5 days of comprehensive training
- Focus on expanding and deepening Python skills
Target Audience
- Experienced programmers familiar with Python basics
- Ability to write simple Python scripts
- Basic understanding of data types and program structures
Description
The Intermediate Python Programming training course is for experienced programmers who want to expand and deepen their Python programming skills. The class starts with a focus on configuring a proper development environment, including editor configuration, code formatters/linters, static type checking, virtual environments, and package management. Then, the class goes deeper into Python concepts such as iteration, specialized data structures, advanced functions, and classes. Next, the focus transitions to the many concurrent programming options within Python. Topics like the GIL, variable locks, and such are covered.
Learning Objectives
- Learn to set up a modern Python development environment with Visual Studio Code.
- Explore how to create virtual environments and manage packages.
- Apply static typing to Python scripts through Type Hints.
- Go deeper into iteration through built-in data types, generators, and comprehensions.
- Leverage specialized data structures and classes provided by the Python standard library.
- Improve script execution with concurrent programming techniques, including multiprocessing and asynchronous programming.
- Learn how better to leverage the file system and networking in Python scripts.
Training Materials
All students receive comprehensive courseware covering all topics in the course. Courseware is distributed via GitHub in the form of documentation and extensive code samples. Students practice the topics covered through challenging hands-on lab exercises.
Software Requirements
Students will need a free, personal GitHub account to access the courseware. Students will need permission to install Python and Visual Studio Code on their computers. Also, students will need permission to install Python Packages and Visual Studio Extensions. If students are unable to configure a local environment, a cloud-based environment can be provided.
